IMPROVEMENT IN CARPENTERS SQUARES.

'Specification forming part of Letters Patent No. 151,254, dated May 26, 187A; application tiled June 28, 1873.

To all rwhom fit may concern:

Be it known that I, JU'sTUs A. TRAUT, of New Britain, county ot' Hartford and Sta-te of Connecticut, have invented certain new and useful Improvements in the Manufacture of Carpenters Squares; and to en able others skilled in the art to make and use the same, I will proceed to describe, referring to the draw- Y ings, in which the same letters indicate like' parts in eachof the figures.

The nature of this improvement will be understood from the specification and drawings. The object is to produce a cheap and perfect square. .f e

In the accompanying drawings, Figure l is a side'view. Fig. 2 is an end section of the .stock and portion of the blade cut through the holding or fastening composition and rivets.

a is the stock. b is the blade, having divisions or a, measuring-scale marked thereon in the common way, with composition passage and rivet-orifices at one end. c are depressions formed in each side ot' the stock, for the purpose of reducing the weight ot' the metal. d is an elongated orifice formed across and 'when the blade is placed and clamped firmly against the bottom of said slit e 'it will be at right angle with the stock; then the molten metal or composition fis poured into the orifice d around the rivets g. After this the stock is finished in the usual way.

What I claim, and desire to secure by Let- The try-square, substantially as herein shown and described, having the stock a and blade b united by the rivets g and composition f.
